The issue also happens with MATE desktop (X11), and no other programms running
(i.e. no Firefox)

LM studio log:

```

I did verify it is using system vulkan libraries (vulkan loader, and the radeon
mesa driver too).


The issue is reproducible, by loading same model, and replying the same
conversation to the same point.
